Technology Feature Brief: Adjustable Line Spacing

Two images of the same article within the CISL reader environment are shown side-by-side. The article in the image on the right has more space between lines of text, compared to the article in the left image. Above the two images a line of text reads “More or less space between lines?” with two arrows, one pointing to each image.

Options to adjust line spacing can impact the accessibility of text and the level of engagement a reader has with the text. Readers value choosing to have the lines of text closer together or further apart.

The Center on Inclusive Software for Learning (CISL) at CAST conducted literature reviews and testing within Clusive, our adaptive and accessible web-based reader designed during the project, to develop Technology Feature Briefs. These briefs are designed for educators, developers, and researchers to find out more about particular features within technology tools, how they’re used, and whether they might be effective in addressing different barriers within a technology environment.
